Abstract
The invention relates to an arrangement for material transport and/or energy transport by means of electric arc. Measured values are transferred with suppression of disturbances from the HF device (,) without appreciable damping of the HF voltage to the electrode (,). A measurement winding (,) is arranged together with a power winding (,) in such a way that effective suppression of disturbances is achieved. Examples of areas of application are thermal spraying, cutting and welding, in particular mechanized TIG welding, but the invention is principally indicated in cases where a spark is established with HF voltage across a gap filled with a gas or a gas/liquid mixture and where at the same time some parameter has to be measured in connection with the spark gap.
